My thought is that connecting two standalone amplifiers, each with its
own protective circuits, bias supplies, etc. with a combiner is kludgy
and likely to lead to problems.
Now the KPA1500 prototype -- that was neat.

I really don't find those kinds of generalizations very constructive ...
or accurate. LOTS of hams live where putting up an additional kilobuck
worth of aluminum is out of the question due to space or neighborhood or
aesthetic considerations. An extra 3 db of transmit power can make a
noticeable difference for them without violating those other
considerations, especially if their local noise levels are low on
receive. Whether that is worth $1K to them will vary from ham to ham.
Besides, for many hams who already have decent antennas on a decent
tower, it would probably take considerably more than $1K to get that
extra 3 db out of more aluminum.
Lastly, if you don't think an extra 3 db can represent a significant
improvement on HF, check out http://www.ab7e.com/weak_signal/mdd.html
Anybody who is an active contester or DXer on HF will often find that
extra 3 db useful in a pileup.
